IMPROVEMENT IN BALlNG-PRESSES.

Specification forming part of Letters Patent No. 1A?, H213, dated April 4, 1865.

T0 @ZZ whom it may concern:

Beit known that I, GEORGE C. PAINE, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Ealing-Press; and I do hereby declare that the following is a full', clear, and exact description ofthe same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a front view of my invention; Fig. 2, a side sectional view of the same, taken in theline .c x, Fig. 3; Fig. 3, a plan or top View of the same; Fig. 4, a side View of a portion of the same 5 Fig. 5, a vertical section of a portion of the same, taken in the line y y, Fig. 2.

Similar letters of reference indicate correspending parts in the several gures.

This invention relates to a new and improved press of that class designed for compressing substaneessuch as cotton, hay,hops, &c-for baling.

The invention consists in the employment or use of toggles, arranged and applied to the press in such a manner as to afford a very compact and efficient mechanism for operating the follower a-nd compressing the substance within the press-box.

The invention further consists in novel and improved fastenings for the side and top doors of the press, whereby the same may be very readily secured in a closed state, and also very readily opened.

To enable th ose skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a pressbox placed in an upright position, and provided with a follower, B, having a metal bar, C, attached longitudinally and centrally to its under side, and provided at each end with a vertical arm, D, in which two friction-rollers, a a, are placed, said rollers work- 'ing in vertical slots l) b in the ends of the pressbox. These arms D have each a lateral pro- `jection, c, which extends through the grooves b, and to these projections c the upper ends of toggle-levers E are attached. rIhe lower ends of these toggle-levers are connected to the base F, on which the pressbox A rests, as shown clearly in Fig-4. It will be seen, by referring to Fig. 4, that each system of toggles is composed of four arms, d d d d', connected by joints e, the arms d being doubled, or two placed side by side. (See Fig. 5.)

G is a shaft placed horizontally in bearings f at one side of the press-box A, and having two pulleys, H H, upon it, and a wheel, I. rlhe pulleys H H are in line with the ends of the press-box, and have each a chain or rope, J, attached to them, said chains or ropes passing around pulleys f/ g g', the two latter g' being at thejoints orjunction ofthe upper and lower arms, and the chains or ropes being attached to the toggles, as shown at h. To the periphery of the wheel I the rope or chain is attached power is used.

From the above description it will be seen that when the follower I3 is down andthe pressbox filled with the substances to be compressed and baled, and the wheel I turned in the proper direction under the pull of the draft-animal or other power which may be applied to it, the pulleys H H will wind up the chains or ropes .I and the two systems of toggles E will be actuated so as to approach a vertical position, the follower B being raised under the movement of the toggles, and under said movement capable of exerting a powerful pressure upon or against the substance within the press-boX. The friction-rollers a a reduce the friction attending the working of the arms D in the vertical slots Z) I).

, K" represents the top of the prcss-box,whieh l. is connected at one side by hinges orjoints 'z3 to the upper end of the press-box. rIhe bar j ot the front or disengaged side of the top K is beveled at each end,as shown at kk, and to the ripper surface ot' said bar a lever, l, is attached by a fulcrum-pin, mf,which passes through the `center of the lever I. To each end of the latter l there is connected a bar, a, and these bars are bent or curved in such a manner that their i outer parts will work through guides o o on the barj. (See Fig. 3.) On the ripper part ofthe press-box A,ateacl1 end of it, there is a catch, L. These catches i are made in the form of loops, so as to receive the beveled ends 7s la ofthe barj. These catches have each a spring, M, bearing against their outer surfaces to throw the catches over the to which the draft-animal is connected if such ends of the bar j when the top K is shoved down in a closed state. The bar j is releasedlfroni the catches L L by actuating alever, N,wl1ich is attached to the front end of the lever Z at right angles, as shown in Fig. 3. The object in having the lever N at right angles with the lever Z is that when the lever is actuated, so as to throw out the bars a n, and the top K raised to a vertical position, the gravity of the lever N will draw inward the bars a a, so that the latter cannot interfere with the `self-locking operation of the top l.

O O represent the side doors of the pressboX, the former being connected at one end by hinges o to the press-box. On the pintles of these hinges there are secured pulleys I IL- one on eaeh-around which a cross-chain, Q, passes, as shown clearly in Fig. 8. By this chain and pulleys the two doors O @,whieh are l at opposite sides of the press-box, are made to open and close simultaneously when either one of the doors is moved. These side doors are kept in a closed state by means of vertical loops or catches It R,which are attached to upright shafts p p, the upper ends of the latter being connected bya rod, q, the ends of which are attached to cranks r r on the shafts p p. By means of this connection the two shafts pp may be simultaneously turned, and the' catches or loops R R made to pass simultaneously over and off from the ends of bars s s of the doors O O.

"Within the upper part of the press-box, at each end of the same, there is secured abeveled plate, S. These plates are simply to facilitate l the discharging of the bale,which isbound, in the usual way, in the upper part of the pressbox before the follower is allowed to descend, the follower beingkept up by a pawl, T,whieh engages with a ratchet, U, on the shaft G.

Having thus described my invention, what claim as new, and desire to secure by Letters Patent, is-

l 1. The peculiar arrangement and construcl tion of the double toggle-levers connected with l the follower l), in combination with the chain l or ropes s s, pulleys H H, and frictionrolll, ers f/,whereby I am enabled to locate the shaft and wheel on the outside of the vertical pressbox, for the purposes described.

2. rlhe leversZ N and bars a meonnected together and applied to the topl ofthe press-box, as shown, in combination with the catches L L, all arranged substantially as and for the purpose herein set forth.

o. The loops or catches RRfapplicd to the shafts p p,connected at their upper ends by the rod q and cranks r o", and arranged relatively with thefsides O O, substantially as and for the purpose herein set forth.

4. The connecting of the pintles of the hinges o of the side doors, O O, by means of the pulleys l? l?, and cross-chain Q, substantially as and for the purpose specified.

GEORGE C. PAINE.
